This application claims benefit of U.S. Provisional Application No. 63/394,230, filed on Aug. 1, 2022, entitled, Implicit Power Saving Operations for a Network-Controlled Repeater (NCR) in Wireless Communications, which is incorporated herein by reference in its entirety.

BACKGROUND

Field

The described embodiments relate generally to power saving operations for a network-controlled repeater (NCR) in a wireless communications system.

Related Art

Wireless communications systems support performance of an amplify-and-forward radio frequency (RF) repeater in a wireless communications system between a base station (BS) and a communications device such as a user equipment (UE). NR Network-controlled Repeaters are described in the 3rd Generation Partnership Project (3GPP) TR 38.867.

SUMMARY

Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for implicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Some embodiments include an NCR that can receive a Downlink Control Information (DCI) format including a first Physical Downlink Control Channel (PDCCH) monitoring periodicity, K_S1, including an integer number of slots, and operate in an On-state for a duration of K_S1based at least on the DCI format. The NCR can detect a skipped PDCCH monitoring periodicity subsequent to K_S1, and operate in an Off-state for a duration corresponding to the skipped PDCCH monitoring periodicity.
In some embodiments, the NCR operates in frequency range 2 (FR2) where a first orthogonal frequency division multiplexing (OFDM) symbol paired with beamforming information corresponds to an On-state for a duration of the first OFDM symbol within a second PDCCH monitoring periodicity, K_S2. The NCR can detect a second OFDM symbol without beamforming information pairing in the second PDCCH monitoring periodicity, K_S2, and operate in an Off-state for a duration of the second OFDM symbol. In some embodiments, the NCR operates with a carrier component (CC) with unpaired spectrum and supports slot configurations time division duplex (tdd)-uplink (UL)-downlink (DL)-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. The NCR can detect from a System Information Block (SIB) of a third PDCCH monitoring periodicity, a flexible OFDM symbol, and operate in an Off-state for a duration of the flexible OFDM symbol.
In some embodiments, the NCR is not configured to receive from or forward to a user equipment (UE), a signal for X_gapOFFtime units, where the X_gapOFFtime units>=Y_OFF, and where Y_OFFcorresponds to a duration for turning off an NCR-Forward (Fwd) component of the NCR at an access link communicatively coupled to the UE. The NCR can operate the NCR-Fwd component at the access link in an Off-state for a duration of the Y_OFFtime units.
In some embodiments, the NCR is configured to receive from or forward to a UE, one or more non-contiguous signals in a second PDCCH monitoring periodicity, K_S2, where a maximum gap between any of the one or more signals is less than X_gapONtime units, and operate an NCR-Fwd component of the NCR at an access link communicatively coupled to the UE, in an On-state for a duration of Y_ONtime units of K_S2. In some embodiments, X_gapOFFtime units represent a duration when the NCR is not configured to receive or forward a signal to the UE, and the X_gapONtime units equals the X_gapOFFtime units, the NCR can operate in an Off-state for a duration of Y_OFFtime units of K_S2.
In some embodiments, the NCR includes an NCR-mobile termination (MT) component and an NCR-Fwd component, where the NCR-MT component and the NCR-Fwd component are communicatively coupled. When the NCR-MT component at a control link uses a different type of radio frequency (RF) component than that of the NCR-Fwd component at a back haul link, the NCR can operate an On-Off state of the NCR-MT component at the control link independently from an On-Off state of the NCR-Fwd component at the back haul link. In some examples, the NCR can determine that the NCR-Fwd component is not configured to receive or forward a signal to a network for X_gapOFFtime units, where X_gapOFFtime units>=Y_OFF, where Y_OFFcorresponds to a duration for turning off the NCR-Fwd component communicatively coupled to the network. The NCR can operate the NCR-Fwd component at the backhaul link in an Off-state for a duration of the Y_OFFtime units based at least on the determination. In some examples, the NCR can determine that the NCR-Fwd component is configured to receive from, or forward to a network via the backhaul link, one or more non-contiguous signals in a second PDCCH monitoring periodicity, K_S2, where a maximum gap between any of the one or more signals is less than X_gapONtime units. The NCR can operate the NCR-Fwd component at the backhaul link in an On-state for a duration of Y_ONtime units of K_S2, based at least on the determination.
In some examples, the NCR can determine that the NCR-MT component is not configured to receive or forward a signal to a network for X_gapOFFtime units, where X_gapOFFtime units>=Y_OFF, where Y_OFFcorresponds to a duration for turning off the NCR-MT component communicatively coupled to the network. The NCR can operate the NCR-MT component in an Off-state for a duration of the Y_OFFtime units, based at least on the determination. In some examples, the NCR can determine that the NCR-MT component is configured to receive from, or forward to a network via the control link, one or more non-contiguous signals in a second PDCCH monitoring periodicity, K_S2, where a maximum gap between any of the one or more signals is less than X_gapONtime units. The NCR can operate the NCR-MT component in an On-state for a duration of Y_ONtime units of K_S2, based at least on the determination.
In some embodiments, when the NCR-MT component communicates with a network via a control link with a same type of RF component as the NCR-Fwd component communicates with the network via a backhaul link, the NCR can operate the NCR-MT component in a same On-Off state as the NCR-Fwd component. The NCR can determine that the NCR-Fwd and NCR-MT components are not configured to receive from or forward to a network, a signal for X_gapOFFtime units, where X_gapOFFtime units>=Y_OFF, where Y_OFFcorresponds to a duration for turning off the NCR-Fwd and NCR-MT functions. The NCR can operate the NCR-Fwd and NCR-MT components in an Off-state for a duration of the Y_OFFtime units based at least on the determining. In some examples the NCR can determine that the NCR-Fwd and NCR-MT components are configured to receive from or forward to a network, one or more non-contiguous signals in a second PDCCH monitoring periodicity, K_S2, where a maximum gap between any of the one or more signals is less than X_gapONtime units. The NCR can operate the NCR-Fwd and NCR-MT components in an On-state for a duration Y_ONtime units of K_S2.

DETAILED DESCRIPTION

Some embodiments include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and sub-combinations thereof, for implicit power saving operations for a network-controlled repeater (NCR) in a wireless network. Cellular network deployments provide wireless access coverage, and different types of network nodes are employed to enable wide area service coverage. Having full-stack cells is desirable, but that may not be always possible (e.g., backhauls may not be available or the solution may not be economically viable.) To improve the performance of an NCR, amplify-and-forward radio frequency (RF) repeater side control information can include On-Off information for efficient interference management and improved energy efficiency. Some embodiments include an implicit indication for power saving operations.
FIG. 1 illustrates an example system for implicit power saving operations for a network-controlled repeater (NCR), in accordance with some embodiments of the disclosure. System 100 includes user equipment (UE) 110, base station (BS) 120, and network-controlled repeater (NCR) 130. NCR 130 can include an NCR-mobile termination (NCR-MT) 133 and NCR-forwarding (NCR-Fwd) 135 connected via link 137. UE 110 may be a computing electronic device such as a smart phone, cellular phone, and for simplicity purposes—may include other computing devices including but not limited to laptops, desktops, tablets, personal assistants, routers, monitors, televisions, printers, and appliances. BS 120 can include but is not limited to a wireless base station, an enhanced node BS (eNB), a fifth generation new radio BS (gNB), or a transmission and reception point (TRP) of a wireless network. NCR 130 exchanges information with BS 120 via control link 123 and/or backhaul link 125.
NCR-MT 133 can be a functional entity that communicates with BS 120 via a Control link (C-link) 123 to enable the information exchanges (e.g. side control information). C-link 123 can be based on a new radio Uu interface. The side control information (SCI) can include instructions for controlling NCR-Fwd 135. In some examples, the SCI can be included in a Downlink Control Information (DCI) format. NCR-Fwd 135 can be a functional entity that performs the amplify-and-forwarding of uplink (UL) and/or downlink (DL) RF signals between BS 120 via backhaul link 125, and between UE 110 via access link 117. The behavior of NCR-Fwd 135 can be controlled according to the received SCI from BS 120 over C-link 123. In some embodiments, the SCI can include explicit and/or implicit On-Off information received by NCR-MT 133 that NCR 130 uses to control NCR-Fwd 135 via link 137, for efficient interference management with neighboring cells and reduced power consumption that results in improved energy efficiency. In some embodiments, NCR 130 can implicitly determine power saving operations for efficient interference management with neighboring cells and reduced power consumption that results in improved energy efficiency of NCR 130. In some embodiments, NCR-MT 133 and NCR-Fwd 135 can be communicatively coupled to processor 140.
FIG. 2 illustrates block diagram of an example wireless system 200 for implicit power saving operations for an NCR, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 2 may be described with reference to elements from FIG. 1 . For example, system 200 may be any of the electronic devices: UE 110, BS 120, or NCR 130 of system 100. In some examples, processors 265 may correspond to processor 140 of system 100. System 200 includes one or more processors 265, transceiver(s) 270, communication interface 275, communication infrastructure 280, memory 285, and antenna 290. Memory 285 may include random access memory (RAM) and/or cache, and may include control logic (e.g., computer instructions) and/or data. One or more processors 265 can execute the instructions stored in memory 285 to perform operations enabling wireless system 200 to transmit and receive wireless communications supporting implicit power saving operations for an NCR described herein. In some embodiments, one or more processors 265 can be “hard coded” to perform the functions described herein. Transceiver(s) 270 transmits and receives wireless communications signals including wireless communications supporting implicit power saving operations for an NCR according to some embodiments, and may be coupled to one or more antennas 290 (e.g., 290 a, 290 b). In some embodiments, a transceiver 270 a (not shown) may be coupled to antenna 290 a and different transceiver 270 b (not shown) can be coupled to antenna 290 b. Communication interface 275 allows system 200 to communicate with other devices that may be wired and/or wireless. Communication infrastructure 280 may be a bus. Antenna 290 may include one or more antennas that may be the same or different types.
FIG. 3 illustrates example 300 of implicit power saving operations for an NCR, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 3 may be described with reference to elements from other figures within the disclosure. For example, portions of example 300 can be generated by BS 120, and processed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 . Example 300 illustrates an implicit power saving operation for NCR 130 that can include NCR-MT 133 communicating with BS 120 via C-link 333 and NCR-Fwd 135 communicating on Fwd-link 335. As an example, Fwd-link 335 can represent communications with BS 120 via backhaul link 125 and/or with UE 110 via access link 117.
In example 300, NCR-MT 133 supports implicit power saving operations on C-link 333, where NCR 130 can assume an Off-state for the associated NCR-Fwd 135, namely, Fwd-link 335 link when an associated Physical Downlink Control Channel (PDCCH) monitoring periodicity (e.g., monitoring occasion (MO)), K_S, is skipped. In some examples, K_Sincludes one or more slots. A slot can include 14 orthogonal frequency division multiplexing (OFDM) symbols, where a symbol can transmit data in the uplink (UL) or downlink (DL) directions. In example 300, NCR-MT 133 can receive Downlink Control Information (DCI) format 310 a via C-link 333 where DCI format 310 a identifies PDCCH MO K _S 340 as receiving and/or forwarding signals. Accordingly, NCR-Fwd 135 can remain in an On-state 320 a for the corresponding PDCCH MO, K _S 340, for transmission of data via Fwd-link 335 (e.g., via backhaul link 125 to BS 120 and/or via access link 117 to UE 110.)
When NCR-MT 133 determines that no DCI formats are received at 310 b or 310 c, NCR-MT 133 determines that there are no signals in PDCCH MOs K _S 342 and K _S 344 to be received and/or forwarded, and PDCCH MOs K _S 342 and K _S 344 are skipped. Accordingly, NCR-MT 133 can inform NCR-Fwd 135 (e.g., via link 137) and/or NCR 130 to enter an Off-state shown as Off- states 320 b and 320 c for a duration of PDCCH MOs Ks 342 and K _S 344, to save power. In the Off-state, NCR-Fwd 135 and/or components of NCR-Fwd 135 (e.g., component at backhaul 125 or component at access link 117) can enter a sleep mode or power save mode to reduce power consumption.
When NCR-MT 133 receives DCI format 310 d via C-link 333, where DCI format 310 identifies PDCCH MO K _S 346 as receiving and/or forwarding signals, NCR-MT 133 can cause NCR-Fwd 135 to enter an On-state shown as 320 d for the corresponding PDCCH MO K _S 346 for transmission of data via Fwd-link 335 (e.g., via backhaul link 125 to BS 120 and/or via access link 117 to UE 110.)
In some embodiments, NCR 130 can receive DCI format 310 a including a first PDCCH monitoring periodicity, K _S 340, and operate in On-state 320 a for a duration of Ks 340 based at least on DCI format 310 a. NCR 130 can detect a skipped PDCCH monitoring periodicity (e.g., K_S 342) subsequent to K _S 340, and operate in Off-state 320 b for a duration corresponding to skipped PDCCH monitoring periodicity, K _S 342.
FIG. 4 illustrates example 400 of implicit power saving operations for an NCR, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 4 may be described with reference to elements from other figures within the disclosure. For example, portions of example 400 can be generated by BS 120, and processed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 . In example 400, NCR 130 can operate with a component carrier (CC) with unpaired spectrum operation that support slot configurations such as time division duplex (tdd)-uplink (UL)-downlink (DL)-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated. In some examples, the slot configurations support OFDM symbols that can be indicated as flexible. When NCR 130 determines one or more flexible OFDM symbols (e.g., detecting from a System Information Block (SIB)), NCR 130 can implicitly enter an Off-state (e.g., sleep or power saving mode) for a duration of the one or more flexible (F) OFDM symbols. In some embodiments, NCR 130 places NCR-Fwd 135 in an Off-state for a duration corresponding to the one or more flexible (F) OFDM symbols detected to avoid forwarding operations that utilize power (e.g., forwarding one or more flexible OFDM symbols.)
In example 400, NCR 130 can determine from a SIB, that slot 410 within PDCCH MO K _S 420 includes DL OFDM symbols 440, flexible (F) OFDM symbols 450, and UL OFDM symbols 460. Accordingly, or NCR-Fwd 135 may enter On-state 470 for a duration corresponding to DL OFDM symbols 440, Off-state 473 for a duration corresponding to flexible (F) OFDM symbols 450, and On-state 475 for a duration corresponding to UL OFDM symbols 460. NCR-Fwd 135 can forward or receive signals via Fwd-link 435 during On-state 470 and On-state 475.
In some embodiments, NCR 130 operates with CC with unpaired spectrum and supports slot configurations tdd-UL-DL-ConfigurationCommon or tdd-UL-DLConfigurationDedicated. NCR 130 can detect from a SIB of a second PDCCH monitoring periodicity, K_S2(e.g., K_S 420), one or more flexible (F) OFDM symbols, and operate in an Off-state 473 for a duration of the one or more flexible (F) OFDM symbols.
In some examples, NCR 130 operates in frequency range 2 (FR2), and an On-state duration of an On-Off Pattern (OOP) can be paired with beam information. For example, NCR 130 can detect one or more OFDM symbols without beamforming information, and enter an Off-state corresponding to the one or more OFDM symbols without beamforming information. In some embodiments, NCR 130 operates in FR2 and a first OFDM symbol paired with beamforming information corresponds to an On-state OFDM symbol duration within K_S1. NCR 130 can detect a second OFDM symbol without beamforming information pairing in a second PDCCH monitoring periodicity, K_S2, and operate in an Off-state for a duration of the second OFDM symbol.
FIG. 5A illustrates example 500 of implicit power saving operations for an NCR, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 5A may be described with reference to elements from other figures within the disclosure. For example, portions of example 500 can be generated by BS 120, and processed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 . NCR 130 can autonomously turn OFF NCR-Fwd 135 function/component at access link 117 for Y_OFFtime units if there is a duration of at least X_gapOFFtime units for which NCR-Fwd 135 is not configured to receive from or forward to UE(s) 110, on any channel or signal, where X_gapOFF≥Y_OFF. In some examples, Y_OFFcan represent a time granularity at a symbol level or slot level for the time NCR 130 takes to turn off RF components (e.g., 1 time unit can equal to 1 OFDM symbol.) In example 500, X_gapOFF=Y_OFF=1 slot. NCR 130 determines that slot N 505 is configured for reception of signals at NCR-Fwd 135, and NCR 130 can place NCR-Fwd 135 in an On-state for ON period 520 a corresponding to slot N. NCR 130 can determine that slot N+1 510 is not configured for reception of signals at NCR-Fwd 135, and X_gapOFF=Y_OFF=1 slot satisfies the condition that X_gapOFF>=Y_OFF. Accordingly, NCR 130 can autonomously place NCR-Fwd 135 in an Off-state for Y_OFFtime unit of 1 slot, shown as OFF period 520 b. In some embodiments, NCR 130 can autonomously place NCR-Fwd 135 in an Off-state for X_gapOFFtime units where X_gapOFFis greater than Y_OFF. NCR 130 can determine that slot N+2 515 is configured for reception of signals at NCR-Fwd 135, and can place NCR-Fwd 135 in an On-state for ON period 520 c.
FIG. 5B illustrates example 550 of implicit power saving operations for an NCR, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 5B may be described with reference to elements from other figures within the disclosure. For example, portions of example 550 can be generated by BS 120, and processed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 . NCR 130 can autonomously turn ON NCR-Fwd 135 (e.g., function or component) at access link 117 for Y_ONtime units, if NCR-Fwd 135 is configured/indicated to receive/forward one or multiple contiguous and/or non-contiguous channel/signal from/to UE(s) 110, where the maximum gap between non-contiguous transmissions (if any) is not more than X_gapON. In example 550, X_gapON=4 OFDM symbols and Y_ON=14 OFDM symbols. NCR 130 can determine that slot N 560 is not configured with reception at NCR-Fwd 135, so NCR 130 can place NCR-Fwd 135 in an Off-state as shown by OFF period 580 a. Slot N+1 570 is configured with reception at NCR-Fwd 135 with non-contiguous transmissions where gap 572=1 OFDM symbol and gap 573=2 OFDM symbols are each less than X_gapON=4 OFDM symbols. Accordingly, NCR 130 can keep NCR-Fwd 135 in an On-state for a duration of Y_ON=14 OFDM symbols shown as ON period 580 b, even though the transmissions on a forwarding link (e.g., backhaul link 125 and/or access link 117) are non-contiguous. In an example, when X_gapOFF=X_gapON, NCR 130 can keep NCR-FWD in an Off-state for a duration of Y_OFF.
When different RF components or different types of RF components are used for NCR-MT 133 at Control link 123 and NCR-Fwd 135 at backhaul link 125, the On-Off-state of NCR-Fwd 135 can be set independently from the On-Off-state of NCR-MT-133. In some embodiments, NCR 130 can autonomously turn OFF the NCR-Fwd 135 function/component at backhaul link 125 and/or NCR-Fwd 135 function/component at access link 117 for Y OFF time units, based on the conditions defined. For example, if there is a duration of at least X_gapOFFtime units for which NCR-Fwd 135 is not configured/indicated to receive/forward any channel/signal from/to a wireless network (e.g., BS 120), where X_gapOFF>=Y_OFF, NCR 130 can autonomously turn OFF the NCR-Fwd 135 function/component at backhaul link 125 and/or NCR-Fwd 135 function/component at access link 117 for Y_OFFtime units. (See FIG. 5A.)
NCR 130 can autonomously turn ON NCR-Fwd 135 function/component at backhaul link 125 and/or NCR-Fwd 135 function/component at access link 117 for Y_ONtime units based on the conditions defined. For example, when NCR-Fwd is configured/indicated to receive/forward one or multiple contiguous and/or non-contiguous channel/signal from/to network, where the maximum gap between non-contiguous transmissions (if any) is not more than X_gapON(e.g., less than or equal to X_gapON), NCR 130 can autonomously turn ON NCR-Fwd 135 function/component at backhaul link 125 and/or NCR-Fwd 135 function/component at access link 117 for Y_ONtime units. (See FIG. 5B.)
In some embodiments, NCR 130 can autonomously turn OFF NCR-MT F 133 function/component for Y_OFF _MTtime units, if there is a duration of at least X_gapOFF _MTtime units for which NCR-MT 133 is not configured/indicated to monitor/transmit any channel/signal from/to the network, where X_gapOFF _MT>=Y_OFF _MT. In some embodiments, NCR 130 can autonomously turn ON the NCR-MT 133 function/component for Y_ON _MTtime units, if NCR 130 is configured/indicated to monitor/transmit one or multiple contiguous and/or non-contiguous channel/signal from/to a wireless network, where the maximum gap between non-contiguous monitoring/transmissions (if any) is not more than X_gapON _MT. In an example, X_gapOFF _MT=X_gapON _MT.
If the same RF components or the same type of RF components are used for NCR-MT 133 and NCR-Fwd 135 at backhaul link 125, NCR 130 may autonomously set On-Off-states of NCR-Fwd 135 and the NCR-MT-133 to be the same. In some embodiments, NCR 130 can autonomously turn OFF both NCR-MT 133 and NCR-Fwd 135 function/component for Y_OFF _MT-Fwdtime units, if there is a duration of at least X_gapOFF _MT-Fwdtime units for which the NCR-MT 133 is not configured/indicated to monitor/transmit any channel/signal from/to the network and NCR-Fwd 135 is not configured/indicated to receive/forward any channel/signal from/to network, where X_gapOFF _MT-Fwd>=Y_OFF _MT-Fwd. In some embodiments, NCR 130 can autonomously turn ON the NCR-MT 133 and NCR-Fwd 135 function/component for Y_ON _MT-Fwdtime units, if NCR-MT 133 is configured/indicated to monitor/transmit one or multiple contiguous and/or non-contiguous channel/signal from/to network and if NCR-Fwd 135 is configured/indicated to receive/forward one or multiple contiguous and/or non-contiguous channel/signal from/to network, where the maximum gap between non-contiguous monitoring/transmissions (if any) is not more than X_gapON _MT-Fwd. In some embodiments, X_gapOFF _MT-Fwd=X_gapON _MT-Fwd.
In some examples, NCR 130 can turn OFF one or more of its corresponding components/functions (e.g., NCR-MT 133 and/or NCR-Fwd 135) after at least a gap Δ_OFFfrom the last transmission/reception, where the gap Δ_OFFcan be either hard-coded and/or semi-statically configured and/or dynamically indicated (e.g., X_gapOFF>=Y_OFF+Δ_OFF). This could be beneficial for taking into account any transient time and/or internal timing misalignment at NCR 130.
In some examples, NCR 130 can turn ON one or more of its corresponding components/functions(e.g., NCR-MT 133 and/or NCR-Fwd 135) before at least a gap A ON before the starting of a first transmission/reception, wherein the gap Δ_ONAON can be either hard-coded and/or semi-statically configured and/or dynamically indicated. This could be beneficial for taking into account any transient time and/or internal timing misalignment at NCR 130.
In some embodiments, the configuration/indication of scheduled forwarding/reception at NCR-Fwd 135 function/component (for access link 117 and/or backhaul link 125) can be implied by combination of configuration/indication of corresponding beams for NCR-Fwd 135 and the UL-DL TDD configuration. For example, when NCR 130 is configured with DL symbol/slot and a corresponding beam, then NCR 130 can turn OFF the RX chain for NCR-Fwd 135 at access link 117.
In some embodiments, NCR 130 can be configured to selectively turn ON or OFF NCR-MT 133 function depending on the scheduled transmission/reception or monitoring occasion (e.g., NCR-MT 133 is not required to turn ON for all of the PDCCH monitoring occasions (e.g., PDCCH monitoring periodicities.)
In some embodiments, NCR 130 can be configured by a wireless network (e.g., BS 120) to apply implicit and/or explicit ON-OFF procedures (e.g., set to On-state and/or Off-state.) In some examples, a single configuration is applied to NCR-MT 133, NCR-Fwd 135 at backhaul link 125 and NCR-Fwd 135 at access link 117. In some examples, a different configuration can be applied to NCR-MT 133, NCR-Fwd 135 at backhaul link 125 and NCR-Fwd 135 at access link 117.
FIG. 6A illustrates example method 600 for an NCR supporting implicit power saving operations, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 6A may be described with reference to elements from other figures within the disclosure. For example, portions of method 600 can be performed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 .
At 601, system 200 can receive a Downlink Control Information (DCI) format including a first Physical Downlink Control Channel (PDCCH) monitoring periodicity, K_S1. For example, in FIG. 3 , system 200 can receive DCI format 310 a that identifies PDCCH monitoring periodicity, K _S 340 as receiving and/or forwarding data in a signal.
At 602, system 200 can operate in an On-state for a duration of K_Sbased at least on the DCI format. For example, FIG. 3 illustrates NCR-Fwd 335 operating in an On-state for an On-state 320 a for duration of PDCCH monitoring periodicity, K _S 340.
At 603, when system 200 detects a skipped PDCCH monitoring periodicity, method 600 proceeds to 605. For example, FIG. 3 illustrates NCR-MT 133 detecting that PDCCH monitoring periodicity, K _S 342 is skipped (e.g., based at least on DCI format 310 b). Otherwise, method 600 proceeds to 607.
At 605, system 200 operates in an Off-state for a duration corresponding to the skipped PDCCH monitoring periodicity. For example, FIG. 3 illustrates NCR-Fwd 135 operating in Off-state 320 b for the duration of PDCCH monitoring periodicity, K _S 342. Method 600 returns to 601.
At 607, when system 200 operates in frequency range 2 (FR2) and detects an OFDM symbol without beamforming information pairing, method 600 proceeds to 610. For example, when NCR-MT 133 determines that one or more OFDM symbols within a second PDCCH monitoring periodicity, K_S2is not paired with beamforming information. Otherwise, method 600 proceeds to 613.
At 610, system 200 operates in an Off-state for a duration of the second OFDM symbol. NCR-MT 133 may implicitly determine that NCR-Fwd 135 should enter a sleep state or power saving state for a duration of the one or more OFDM symbols that are not paired with beamforming information. Method 600 returns to 601.
At 613, when system 200 operates with a carrier component (CC) with unpaired spectrum and detects a flexible (F) OFDM symbol, method 600 proceeds to 615. For example, FIG. 4 illustrates NCR-MT 133 detecting flexible (F) OFDM symbols 450 within slot 410 of PDCCH MO K _S 420, and method 600 proceeds to 615. Otherwise, method 600 proceeds to 617.
At 615, system 200 operates in an Off-state for a duration of the flexible OFDM symbol. For example, FIG. 4 illustrates NCR-MT 133 causing NCR-Fwd 135 to enter a sleep or power saving state for a duration of flexible (F) OFDM symbols 450 shown as Off-state 473. Method 600 returns to 601.
At 617, when system 200 (e.g., NCR 130) is not configured to receive from or forward to user equipment (UE) 110, a signal for X_gapOFF, where X_gapOFF>=Y_OFF, method 600 proceeds to 620. For example, FIG. 5A illustrates NCR-MT 133 determining that Slot N+1 510 is not configured to receive and/or forward data to UE 110, where a duration of Slot N+1 510 is greater than or equal to Y_OFF. Y_OFFtime units can equal a time granularity at a symbol level or slot level for the time NCR 130 takes to turn off RF components (e.g., RF components of NCR-Fwd 135). In example 500, X_gapOFF=Y_OFF, and method 600 proceeds to 620. Otherwise, method 600 proceeds to 623.
At 620, system 200 operates NCR-Fwd 135 (e.g., component at access link 117) in an Off-state for a duration of the Y_OFFtime units. In example, 500, NCR-MT 133 can cause NCR-Fwd 135 to operate in an Off-state for a duration shown as OFF period 520 b. Method 600 returns to 601.
At 623, when system 200 (e.g., NCR 130) receives from or forwards to UE 110, one or more non-contiguous signals of a second PDCCH monitoring periodicity where a maximum gap between any of the one or more signals is less than X_gapON, method 600 proceeds to 625. For example, in FIG. 5B, system 200 can determine that one or more non-contiguous signals of Slot N+1 570 includes gaps 572 and gaps 573 that are less than X_gapON(e.g., X_gapON=4 OFDM symbols); method 600 proceeds to 625. Otherwise, method 600 proceeds to 627.
At 625, system 200 operates NCR-Forward (Fwd) 135 (e.g., component) in an On-state for a duration of Y_ONtime units of the second PDCCH monitoring periodicity. In FIG. 5B, for example, Y_ON=14 OFDM symbols, and system 200 can operate NCR-Fwd 135 in an On-state for Y_ON=14 OFDM symbols shown as ON period 580 b. Method 600 returns to 601.
At 627, when system 200 determines that NCR-mobile termination (MT) 133 and NCR-Fwd 135 use different types of RF components, method 600 proceeds to 630. When system 200 determines that NCR-MT 133 uses cellular (e.g., 3GPP New Radio (NR)) and NCR-Fwd 135 uses cellular (e.g., Long Term Evolution (LTE)) and/or WiFi components, for example, method 600 proceeds to 630. Otherwise, method 600 proceeds to 653 of FIG. 6B.
At 630, system 200 operates On-Off states of NCR-MT 133 and NCR-Fwd 135 components independently. For example, NCR-MT 133 components may operate in an On-state while NCR-Fwd 135 components may operate in an Off-state. Method 600 proceeds to 633 of FIG. 6B.
FIG. 6B illustrates another example method 680 for an NCR supporting implicit power saving operations, according to some embodiments of the disclosure. For explanation purposes and not a limitation, FIG. 6B may be described with reference to elements from other figures within the disclosure. For example, portions of method 600 can be performed by NCR 130 that includes NCR-MT 133 and NCR-Fwd 135 of FIG. 1 , or system 200 of FIG. 2 .

At 634, system 200 operates the NCR-Fwd component in an Off-state for a duration of the Y_OFFtime units (see FIG. 5A). Method 600 returns to 601 of FIG. 6A.
At 635, when system 200 determines that NCR-Fwd 135 receives from/forward to a network one or more non-contiguous signals of a second PDCCH monitoring periodicity where a maximum gap between any of the one or more signals is less than X_gapON(see FIG. 5B) method 600 proceeds to 637. Otherwise, method 600 proceeds to 640.
At 637, system 200 operates NCR-Fwd 135 in an On-state for a duration of Y_ONtime units of the second PDCCH monitoring periodicity (see FIG. 5B). Method 600 returns to 601 of FIG. 6A.
At 640, when system 200 determines that NCR-MT 133 is not configured to receive/forward a signal to a network for X_gapOFFtime units, where X_gapOFFtime units>=Y_OFF(see FIG. 5A) method 600 proceeds to 643. Otherwise, method 600 proceeds to 645.
At 643, system 200 operates NCR-MT 133 in an Off-state for a duration of the Y_OFFtime units (see FIG. 5A). Method 600 returns to 601 of FIG. 6A.
At 645, when system 200 determines that NCR-MT 133 receives from/forward to a network, one or more non-contiguous signals of a second PDCCH monitoring periodicity where a maximum gap between any of the one or more signals is less than X_gapON(see FIG. 5B) method 600 proceeds to 647. Otherwise, method 600 returns to 601.
At 647, system 200 operates the NCR-MT component in an On-state for a duration of Y_ONtime units of the second PDCCH monitoring periodicity (see FIG. 5B). Method 600 returns to 601 of FIG. 6A.
At 653, (e.g., from 627 of FIG. 6A) system 200 NCR-MT 133 and NCR-Fwd 135 use same type of RF component. When system 200 determines that NCR-Fwd 135 and NCR-MT 133 are not configured to receive from/forward to a network, a signal for X_gapOFFtime units, where X_gapOFF>=Y_OFFtime units (see FIG. 5A), method 600 proceeds to 655. Otherwise, method 600 proceeds to 657.
At 655, system 200 operates NCR-Fwd 135 and NCR-MT 133 in an Off-state for a duration of Y_OFF(see FIG. 5A). Method 600 returns to 601 of FIG. 6A.

Otherwise, method 600 returns to 601 of FIG. 6A.
At 660, system 200 operates NCR-Fwd 135 and NCR-MT 133 in an On-state for a duration of Y_ONtime units of the second PDCCH monitoring periodicity (see FIG. 5B). Method 600 returns to 601 of FIG. 6A.
